Benchmark for Surface Imaging in the Subnanometer Set by Zeiss

Facebook X LinkedIn Email
Carl Zeiss announced it has set a new world record resolution benchmark for scanning electron and ion microscopy, pushing scanning beam technologies beyond current limits. Using its Orion helium-ion microscope, a surface resolution of 0.24 nm was repeatedly achieved (25-75 percent edge-rise criterion) on various samples. This resolution, which is close to the diameter of a single atom, is three times better than even the most sophisticated scanning electron microscopes can achieve today with the same surface sensitivity, the company said. The secret behind its extreme high resolution lies in...Read full article

    diffraction
    As a wavefront of light passes by an opaque edge or through an opening, secondary weaker wavefronts are generated, apparently originating at that edge. These secondary wavefronts will interfere with the primary wavefront as well as with each other to form various diffraction patterns.
    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
